Old Ordnance Survey Inch to the Mile Maps

These maps normally cover an area of about 18 miles by 12 miles and are especially good at showing railways, roads and canals, and at giving
a broad view of a wider area. Each includes an introduction and a more detailed map of a small town or village.
They are available through our On-line Mapshop

This Inch to the Mile map covers the area around and to the west of Brecon, including the upper reaches of the River Usk.
Coverage stretches from Brecon and Llanfrynach westward to the border with Carmarthenshire and Mynydd Myddfai; and from Merthyn Cynog southward to
Moel Feity. The Brecon Beacons National Park today covers the lower half of the map, and apart from Brecon itself the area is
overwhelmingly rural. On the back we include a large scale map of Trecastle.

It is not possible to list the many hamlets, farmsteads and other topographical features shown on these maps. However, you may find it useful if we list the towns and
principal villages or church parishes that are included on this map:
